Economizer for heat recovery from flue gas

Hexonic - Economizer for heat recovery from flue gas

We have designed and manufactured a shell and tube heat exchanger for heat recovery from flue gases resulting from biomass combustion. The exchanger has been successfully operating in a biomass-fired boiler house in France since 2015.

Burning biomass is less harmful for the environment than burning fossil fuels, because the content of harmful elements in biomass is lower than in coal.
